Interesting question this. Notts CC have had a temporary crossing using portable equipment (I think)on Kegworth Road in Gotham for ages, must be more than 12 months. No lining whatsoever. How long could something like that be justified.
To be fair, you’re covered with the primary signal if the local drunks decide to partake of a bit souvenir gathering… but for the sake of a bit of thermo, I’d be inclined just to slap some lines down anyway. Should only be a few quid!
I’ve a set of long term temporary signals in place as part of a much larger non-signals related project. They’ve to be in place for approximately 15-18 months and comprise proper Siemens heads sitting in NAL concrete blocks all operating through a 950 controller that’s hooked into my RMS fault monitoring system.
The query that’s been asked is should these be marked up on site with STOP lines or, because they’re still temp lights, will signs to 7011.1 do along with all the other requsite temporary signing?
